["制冷剤換熱の問題",,"当本公司是焦炉煤气液化天然气厂时,制冷�CNT有氮气甲烷乙烯丙烷异戊烷。制冷�CNT进冷箱的温度上升时冷箱上部温度反而下降。液相节流阀前后温度都是下降的趋势气相节流阀前后温度无明显变化。制冷�CNT出冷箱温度是上升的。我想问一下是什么原因造成这种现象冷箱上部温度为什么会下降?",,"冷箱圧力高温度也会上涨因为压缩机做功多压効果明显温度会降低",,"制冷剤圧力没有明显变化啊"]

我厂是焦炉煤气制液化天然气厂,制冷剂有氮气甲烷乙烯丙烷异戊烷,制冷剂进冷箱的温度上升时,冷箱上部温度反而会下降,液相节流阀前后温度都是下降的趋势,气相节流阀前后温度无明显变化,制冷剂出冷箱温度是上升的。我想问一下是什么原因造成这种现象,冷箱上部温度为什么会下降?

进冷箱压力高,温度也会涨,因为压缩机做功多,压力高节流效果明显,温度会降低

制冷剂压力没有明显变化啊
